Based on the usage that you've described I'll offer this.
Like I said I've been surprised by how well the 710 in D2 (Had 3 over the years) has held up as far as my usage. Ounce for ounce, considering it's light weight and slim profile I think it's an extremely well made, strong, reliable knife, that also offers good blade size. It is far stronger then it's appearance and feel would suggest. I have no question that the 710 will perform well under heavy usage, the strength is there.
However, having said the above, Although the 710 can handle hard use it would not be my first choice for what I would personally consider a "dedicated" hard use folder. Not because of personal experience which has been very positive or some inherent lack of strength but rather other models that are available that offer greater strength overall and are specifically designed to handle harder use on a regular basis.
If your looking for a dedicated hard use folder where overall strength is the primary need I would suggest from the current BM line up the Contego, Adamas, or Rift. These Black Class knives were designed with regular harder use in mind. I want to stress this takes nothing away from the 710. If it were the only knife I owned I'd feel very well equipped for whatever my cutting needs were..
The 710 is a great knife, a classic, one of the all time greats and for good reason. I think everyone should own at least one and it's no slouch when it comes to strength or hard use. I'd only suggest that if you are looking for a knife that is specifically designed as a harder use folder where shear strength is your primary concern you consider some of the other BM models I've mentioned. Then again, if the 710 is your knife of choice, you still can't go wrong in any way,it won't let you down!
Hope this helps and best of luck!
